MONEY WHORE

Kevin Hart tried to gouge Sony Pictures out of extra money -- on top of the millions he already received -- for promoting his movie on social media, and a Sony exec groused, "I'm not saying he's a whore, but he's a whore" ... this according to the latest in the Sony Leak.

Clint Culpepper, a studio exec, sent several emails to studio heads, complaining that Kevin made $3 million and then $4 million for his last 2 Sony flicks, yet when he was asked to tweet out a plug for "Think Like a Man Too," his agent balked because he felt Kevin's expertise in social media was worth additional money.

Culpepper suggests they put the screws to Kevin, writing, "I'm tempted to suggest we call his bluff. If he doesn't do his normal routine, his film will not open as well and his brand will appear diminished and he will -- in fact -- be f***ing himself because we have his next 2 immediate films."

The leakers are in high gear, because the movie they want killed -- "The Interview" -- is slated for a premiere tomorrow night.
